Touch-less Fingerprint Recognition System at Airports

Security is the most important aspect of Technology. To reach the goals of security, every business or industry have their own security systems. So, the airline industry is no behind the others. Till date the airline reservations and airplane boarding were done examining the identity cards such as License, PAN Card or Passport. But these can be manipulated and security can be breached. To avoid this, some airports have used the concept of biometrics. In this, the authentication of the boarders can be done by using some biometric techniques like Finger Print Recognition, Face Recognition, etc. For fingerprint recognition, fingerprint sensors are used. Most of the sensors available today use "touch" method since it is simple and little training is required. But there are some drawbacks of touch based fingerprints. To overcome the above limitations, touch-less fingerprint technology came into existence This paper presents an introduction to touch-less fingerprint recognition system using a digital camera and how it can be used in the airline industry. This paper also discusses both the disadvantages and the advantages of touch-less fingerprint systems along with the approaches to capture touch-less fingerprint.
